    This is the most ******* business ever. No response. I had a problem with their device, tried my best to talk to them about it, and all they done was block my phone calls and ban me from their property. I hadn't even attempted to go there. My Pastor from my home church had to return device and the manager didn't even have the decency to come out to front desk and talk to him. I offered to pay whatever they wanted to uninstall the device, but the manager didn't want to hear that. All they care about are charging people for installation and then any fees that they can get for whatever reason. Whether it be the cause of the client, or the cause of their faulty device. If you refuse to pay their fees for a faulty device, on their part, they can and WILL lock your car to where it won't start. This certain location, this manager is *********** He doesn't care if you have to get to work, he doesn't care if it's the device malfunction, all he cares about is holding your car over your head. Either pay the for the device malfunction or you won't be able to drive your car. I actually took him to court and he didn't have the decency to show up!!! Life Safer at 5446 Hilton Industrial Way Knoxville TN is such a *****!! PLEASE!!! I BEG YOU, DO NOT TRUST THIS MAN!!! He's all about that dollar. He's all about filling his pocket. He DOESN'T CARE ABOUT YOU!!! I PROMISE!!! He doesn't care if you lose your job. He doesn't care if you lose your home . He doesn't care if YOU GO TO JAIL!!! ACTUALLY, HE WILL INSIST ON IT!!! The worst place ever to do business with

    This client is angry about the legal process of the interlock. We did install the interlock on his vehicle. His DUI charges were form Virginia and Virginia laws prohibit any interlock installer from removing the device until the case is reviewed by the state and written permission is issued to the provider to remove the device. He did not follow the proper steps required by Virginia and they denied the removal. We have absolutely no control over when the removal can be done. Mr ******* is angry because we refused to break the law and remove the device, which would result in us being fined and our license being pulled. I even spent about 30 minutes prior to install explaining to the client that I have absolutely no control over state regulations. I did block his number because he repeatedly called our business phone every 2-3 minutes threatening us if we did not remove the device. This compliant should be directed towards Virginia since that is who denied the removal.
